Sounds all the word of an electrical grimlin. Stator, Voltage reg, ECU, Ground, wire grounding out?
Def not a intake charge temp issue the ADA adjust for the temps (almost all kits are ADA from 2008 and up) and wile yes a cooler charge temps are better like a mini cooler ect it is not the issue.
Kit doesn't have the ADA, but only running low boost at 9500 feet and higher.
Runs consistently, so I doubt that it is electrical. Especially since it has had 3 different ecu's, 2 voltage regulators, and the stator was ohm'd out for gnd. and ohms. The warmers were also ohm'd out.
